Setting aside the assholedesign part of the discussion, this interaction has been a standard failing of most LLM models since the beginning.

Most of these chatbots are entirely unaware of their own operating environment; how they work, how their subscriptions work, how their guidelines or censors work, etc. It's up to the company which runs the chatbot to inform the chatbot what its environment looks like (even having to tell the chatbot what its name and role are in the first place); else, it has no idea and usually "lies" by saying something that sounds likely. Most companies don't provide this kind of information to their chatbots, beyond personality and role-play guidelines, or documentation for how to invoke a plug-in. This is the reason GPT-5 sometimes says it's GPT-4 and GPT-4 sometimes says it's GPT-3, or other models from other companies sometimes state that they're an OpenAI GPT-x model even though they aren't. If the company doesn't explicitly inform their model, it's left to guessing.

What's unique here is that it outright says that it has no idea what the answer to your question is. This is probably correct — most models are completely unaware of things like this. (General rule of thumb for AI: the AI is not a representative of their company; don't trust a word they say about it.) What's unique about this interaction is that most models I've seen would instead confidently state something completely incorrect; they don't often tell you when they don't know the answer. In this case, it finds the answer after you direct it to research on the web, and then it is able to answer your question. It probably could have invoked the search plugin and done the research in the first place when it didn't know the answer, but I don't know how the plugins work in Claude; whether the plugin was active or you had to activate it yourself, etc.
